The most retweeted tweets

The retweet numbers are close to the values that Twitter
has for the tweets, which means that I can't have messed up too
much (I wouldn't expect perfect agreement since Twitter does not
guarantee that any search will return all matching tweets).

A look at what's popular

The most re-tweeted accounts.

Twitter account

Number of re-tweets

The accounts that are mentioned the most.

Twitter account

Number of mentions

It is not really that
surprising that the most re-tweeted accounts also appear in
the
most-mentioned table.

The accounts that are replied to the most (this
excludes retweets)

Number of replies made

What are the most-used hash tags?

HashTag

Number of mentions

Note that #aas221 and #hackaas have an
advantage here since the search I used was for
'aas221', 'aas 221', or 'hackaas'.

What URLs are mentioned the most?

URL

Number of mentions

The counts in this table jumped significantly - at least for
the top URL - on February 12th since I updated my code
to calculate the "true" URL - i.e. after following through
all the link-shorteners you find on Twitter.
Since there are some common query strings seen in URLs on
Twitter which can lead to "missing" counts, I removed the
following query terms for most URLS:
utm_source, utm_medium, utm_campaign,
goback and cid. For YouTube links I dropped the
feature term, which is why the
"Fund Me, Maybe" video just sneaks in at number 6.
The choice was made after reviewing the URLs.

What program or web site was used to tweet?

Publisher

Number of tweets

Note that this table is created from the
tweets
()
that included this information.

How many different programs were used by a user?

Number of programs

Number of tweets

I have not (yet?) looked into the "multi-program" cases to
see if it is people with multiple devices - perhaps a
smart phone during the conference and a browser/desktop
application back in the hotel room - or something else.

How chatty were people?

Below I show the distribution of the number of times
an account tweeted (this excludes retweets made by the
account). The graph has been cut off
to focus on the low-numbers
since there are
some users with upwards of 100
tweets.
The number of tweets used in this
analysis is
and the graph accounts for
of this total.

This plot shows the number of retweets by a user;
as can be seen most people made 1 retweet,
although there is a significant fraction
() who
made none.
There are
users that have been excluded by the cut off at
; the maximum
number of retweets by a user is
.

How popular is retweeting?

Below I show the distribution of the number of times
a tweet was re-tweeted. The graph has been cut off
to focus on the low-numbers; as shown above there
are tweets that have more than 70 retweets, but it is
only of the population.
The number of tweets used in this
analysis is .

How long did it take for retweets to occur?

Here we look at the distribution of "retweet times" -
i.e. the time between the original tweet and when it was
re-tweeted.
There are two graphs; the first is limited to
one day, and so excludes
of the distribution.
The second graph shows all the tweets, but uses a
much-larger bin size.
The number of retweets used in this
analysis is .

Would people be interested in seeing the same
distribution but for replies to tweets
(i.e. conversations)?

This is not a popularity contest

I am interested in seeing whether we can split up the
population, so I wonder if the distribution of number of followers
vs followed for each person may tell us something.
Given the Twitter etiquette of reciprocity, I expected
there to be a trend along the y=x line, here
shown as the diagonal line. I have excluded the
accounts who either have no follows or followers.
Since the number of follows and followers for an account
varies with time, I have used the maximum value for each
account reported by the Twitter search.

The soft limit of 2000 followers can be seen as the
upper bound on most of the users; I have added a blue
rectangle showing the area where the number of follows
is more than 2000 but the number of followers is less
than 2000 to highlight this area. The limit is explained
in the Twitter documentation on
Are
there additional limits if you are following 2000+
accounts?.
